How to properly eliminate and remove an OBC???

AH! [mention]Sergio [/mention] so you mean I can de pin the white wire as well, tie the blue wire in the connector directly to the blue wire from the summit 2, and I should be good to go?

When I took the charge port off, there was a glass covered fuse of some sort, and the grey wire had the little yellow fuse holder as well. All of that is gone now, and I was just trying to utilize the lockout feature cause my wife doesn’t pay attention to these sort of things. Last thing I need is a broken charge port I am in the process of building. I will send pictures when I’m done with that.

Correct, You don't need any wires or fuses from the charger receptacle.

The Blue wire from the Summit will go directly to the Blue wire that is in harness side of the OBC 6-pin connector.

The White wire (+48v power) needs to be taped so it does not short against anything and it does not connect to anything.

Make sure you run the Lester Connect APP and set the charger for OnBoard use.

Gonna go try this now. Thanks for your input here, I knew it couldn’t be this difficult. Having the onboard charger is a game changer for us. No more worrying about charging, especially when I jump to a big boy controller and motor!

Nice! Where did you get that plug?

Those plugs are also used for "shore power inlets" for boats.

Yep! Had a buddy that makes stuff out of heavy duty plastic so he made the rings and I just drilled pilot holes and mounted it up

1 - Put tow/run switch in TOW.
2 - Disconnect main positive and main negative battery terminals.
3 - Locate the 10 gauge black wire at the back of the OBC that comes from the charger receptacle. Cut this wire and crimp on a 5/16" 10 gauge ring terminal.
4 - Disconnect the grey wire with the fuse holder from the back of the OBC. Cut this wire off at the back of the charger receptacle, as it will not be used again. Cut the opposite end of the grey wire near the OBC and pull it out of the wire loom entirely, leaving only the 1- gauge black wire mentioned in the previous step. Discard the grey wire.
5 - Remove OBC from the vehicle
6 - Cut the 6-pin connector off of the OBC
7 - Dis-assemble the 6-pin connector that you removed from the OBC and de-pin it, leaving only the white wire and the blue wire in the connector. Put retaining clip and rubber gasket back on the plug
8 - Using a butt-connector or a solder joint, connect the white wire and the blue wire together.
9 - Plug the 6 pin connector back into the wire harness on the car.
10 - Connect the 10 gauge black wire from step 3 to either the B- post of the controller (or negative junction block on DS IQ), or to the main negative battery terminal
11 - Install a new 6 gauge cable from main battery negative to the controller B- terminal. This will replace the wire that was going through the hole in the OBC. You can re-use that same wire if you wish. You'll just have to cut the terminall off of it to pull it through the hole in the OBC and install a new terminal on it in order to re-use it.
12 - Connect positive and negative battery terminals
13 - Flip Tow/Run Switch to RUN.

So I'm having an issue with this since I switched to Lithium Batteries. I believe its because I'm missing a ground for the solenoid because I not only removed the OCB, but the charging port as well. Which according to steps #3 and #10 I still need?
